alesis to go. i saw them both and i can say that the alesis has superior design like/in terms of the woofer, tweeter, casing, etc. but it would be more expensive than the MS40.
for more options, you can try checking Samson Resolv 40a or Multimedia 4 in audiophile shops. bnew at around P8k only. close to a price of the MS40 and a more hardcore studio monitor
. i personally recommend the 40a cause im using one... hahaha. quite good, really. near-field loud enough for my room.
by the way, powered lahat yang mga yan.
